Abstract
A system includes a block having a cylinder, a cylinder head, a cylinder liner, and a gasket. The cylinder liner includes a recess formed into a top surface of the cylinder liner. The cylinder liner is configured to line the cylinder about a piston. The gasket is disposed in the recess between the cylinder head and the cylinder liner. The recess includes a bottom surface. At least a portion of the bottom surface includes a tapered portion and a depth of the tapered portion increases along an inward radial direction of the cylinder liner.
Claims20
A system, comprising:
- a block having a cylinder;
- a cylinder head;
- a cylinder liner comprising a recess formed into a top surface of the cylinder liner, wherein the cylinder liner is configured to line the cylinder about a piston;
- and
- a gasket disposed in the recess between the cylinder head and the cylinder liner, wherein a bottom surface of the gasket is orthogonal to a central axis of the gasket, and the bottom surface extends from an inner radial surface of the gasket to an outer radial surface of the gasket;
- wherein the recess comprises an additional bottom surface, the additional bottom surface comprises:
- a flat portion configured to engage the bottom surface of the gasket;
- and
- a tapered portion, wherein the tapered portion is tapered relative to the bottom surface;
- wherein a gap is defined by the bottom surface and the tapered portion.
A system, comprising:
- a cylinder liner comprising a recess formed into a top surface of the cylinder liner, wherein the cylinder liner is configured to line a cylinder about a piston;
- and
- a gasket disposed in the recess, wherein a bottom surface of the gasket is orthogonal to a central axis of the gasket, and the bottom surface extends from an inner radial surface of the gasket to an outer radial surface of the gasket;
- wherein the recess comprises an additional bottom surface, the additional bottom surface comprises:
- a flat portion configured to engage the bottom surface of the gasket;
- and
- a tapered portion, wherein the tapered portion is tapered relative to the bottom surface;
- wherein a gap is defined by the bottom surface and the tapered portion.
A method, comprising:
- inserting a gasket into a recess formed into a top surface of a cylinder liner, wherein the cylinder liner is configured to line a cylinder about a piston, wherein a bottom surface of the gasket is orthogonal to a central axis of the gasket, and the bottom surface extends from an inner radial surface of the gasket to an outer radial surface of the gasket;
- mounting a cylinder head over the gasket and a top portion of the cylinder liner;
- and
- applying a clamp load to the cylinder head, wherein at least a portion of the clamp load is transmitted through an outer radial portion of the gasket to the cylinder;
- wherein the recess comprises an additional bottom surface, the additional bottom surface comprises:
- a flat portion configured to engage the bottom surface of the gasket;
- and
- a tapered portion, wherein the tapered portion is tapered relative to the bottom surface;
- wherein a gap is defined by the bottom surface and the tapered portion.
